i wrote about recaptha a few days ago. after it’s been tested by me and several friends who have visited this blog. i found it’s difficult, not just difficult but it’s in the state that could be called as ‘very difficult.’ even i typed the wrong character so many times! the text is not just distorted and twisted, each of them has a strikethrough line crossed which makes it even more difficult to read.

* internet archive scans 12,000 books a month.
* by typing two vocabulary from recaptcha, you can help deciphering images that computer doesn’t recognize.
* recaptcha is a project from the school of computer science at carnegie mellon university.

p.s. personally i think they should create a website for people to voluntarily access and just type the vocabulary directly. i wouldn’t mind going in and type 10 vocabulary everyday.
